Your VSS should be locate at the tail of the tranny, very close to the left axle shaft, with one retaining bolt. Cant clean a sensor, since its full of electronics.
btw, some possible symptons of a bad vss. -the speedometer falls to zero; -simultaneously the O/D light starts flashing; -the check engine light comes on; -no overdrive...engine revs climb to ~ 4000 rpm -ATx seems a bit confused...need to manually select some gears and a bit sluggish in upshifting. -no other prior symptoms, car was shifting fine and all gears were available.
